I think that was pretty harsh, and I like Simon. But I also think that these people sign a release before they go on camera and audition... and they have to know they can't sing. They HAVE TO! I think if you sign that release, and put yourself out there, knowing the judges are critical, then you're asking for it... even if some of the comments are uncalled for. You were warned ahead of time. Right?
OK, I sing. I did talent shows all through high school, and my Mom would tell me when I would attempt to sing a song that was NOT in my range. Even if she didn't tell me, I wouldn't have felt comfortable with it, knowing I simply couldn't hit the notes right. I know my limits, and I know there are certain songs I can sing great, but there are others that I can't do. You would think these parents and friends would tell these people the TRUTH!
